While doing a server migration, it happens that some traffic still go to the old machine because the DNS servers are not yet synced or simply because some people are using the IP address instead of the domain name....
By using iptables and its masquerade feature, it is possible to forward all traffic to the old server to the new IP.
This tutorial will show which command lines are required to make this possible.

Vyatta is a Linux based distro that ease the set up of VPN, Routers, antivirus.... It has a really small footprint on your system as it only requires something like 800M to be installed and is based on Debian. On the top of that, it offers configuration wrappers to facilitate service settings.

Some of the use cases could be:

Linux is a perfect platform to act as a router/gateway.
In this tutorial, I will explain how to set up a Linux box to operate as a network router. The box will provide the following services:

When copying files over the network, the files informations can be modified.
When using cp, one can avoid this issue by using the -a which will do the copy in archive mode, meaning that it will keep the links, preserve mode, ownership and timestamps and the copy is recursive.
the solution to this over the network is rsync alongside with ssh.

The Intel wireless card 4965 AGN does not work properly on ad-hoc networks since hardy and kernel 2.6.24 or around, network-manager can't get it to use the mode ad-hoc and a standard configuration like:

$ sudo iwconfig wlan0 essid myessid mode ad-hoc channel X key s:mykey13charss
$ sudo dhclient wlan0

will fail to get an ip except a long battle at dhclient'ing around.
I managed to get a process to get things working faster.
